Okay, more research - I reverted back to the dist php.ini file and the
crash no longer happens. Regressing through the changes I had made
I've discovered that this crash only happens if PHP 4.x compatibility
is enabled. i.e.
zend.ze1_compatibility_mode = On

Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
Can't reproduce it under Linux with latest snapshot.

Description:
------------
Operating System: Windows 2000 Server
PHP Version: 5.0.3 and binary snapshot 200502030930
Apache versions: 2.0.52 and 1.3.31
I am using running the open source CMS system Mambo with the com_events
component. In some circumstances the code in this component would crash
my installation.
After some tracing I narrowed the crash down to a small piece of code
whereby the first element in a singleton array is re-assigned to a
variable name the same as the originating array(See code example).
By reassigning the array element to a new different variable name this
crash can be avoided.
Reproduce code:
---------------
<?php
$o->id = 77;
$o->name = "Aerospace";
$a[] = $o;
$a = $a[0];
print_r($a);
?>
Expected result:
----------------
stdClass Object ( [id] => 77 [name] => Aerospace )
Actual result:
--------------
404 page not found error and Apache logs show a crash where Apache is
forced to restart.
In Apache 2
child process exited with status 3221225477 -- Restarting.
